The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Based on the problems that the interior of a barrel assembly of the existing drum washing machine is very humid after clothes are washed, bacteria are easy to breed, peculiar smell is easy to generate, and secondary pollution can be caused to the subsequently washed clothes.
Specifically, as shown in fig. 1 and 2, the drum washing machine of the present invention comprises a cabinet 1 and a drum assembly disposed in the cabinet 1, the drum assembly comprises an outer drum 2 suspended in the cabinet 1 by a plurality of elastic damping members, an inner drum 3 rotatably disposed in the outer drum 2, and a window gasket 4 connected to the outer drum 2, the window gasket 4 is further connected to a laundry input port of the cabinet 1, the inner drum 3 is driven by a combination of a motor and a belt or by a direct drive motor, a door glass of the drum washing machine can be closely attached to the window gasket 4 to achieve sealing when closed, the drum washing machine further comprises a laundry treating agent input box 5 (such as a detergent box and a softener box) and a water inlet pipe, an inlet of the water inlet pipe is communicated with the laundry treating agent input box 5, an outlet of the water inlet pipe is communicated with the drum assembly, the laundry treating agent and water are injected into the outer drum 2 together through the water inlet pipe after external water enters the laundry treating agent input box 5, the laundry treating agent putting box 5 is communicated with the outside, the inlet of the water inlet pipe is higher than the outlet of the water inlet pipe, and the water inlet pipe is preferably communicated with the outer barrel 2. When the drum washing machine executes a washing program, water is filled into the outer drum 2 through the water inlet pipe until reaching a washing water level, then the water inlet is stopped, and at the moment, water still exists in the water inlet pipe and forms a water seal.
As shown in fig. 1, the drum washing machine of the present invention further includes an air inlet pipe 7 for communicating the outside with the drum assembly, and a siphon device connected to the water inlet pipe, wherein an air inlet fan 8 is provided in the air inlet pipe 7, and the siphon device is configured to discharge the water in the water inlet pipe when the water in the water inlet pipe reaches a siphon height, so that the water inlet pipe is communicated with the outside. The ventilation control method of the invention comprises the following steps: acquiring the current of the air inlet fan 8 under the condition that the air inlet fan 8 is started; if the current of the air inlet fan 8 reaches a preset current value, water is injected into the water inlet pipe so as to trigger the siphon device to discharge the water in the water inlet pipe, and then the air is ventilated into the cylinder assembly; and if the current of the air inlet fan 8 does not reach a preset current value, directly ventilating the cylinder assembly, wherein the preset current value is preferably the corresponding current value when water in the water inlet pipe completely forms a water seal. Through the detection and the judgement to the current of air inlet fan 8, can reflect whether the water in the inlet tube has formed the water seal, when the current of air inlet fan 8 reached preset current value, explain that the water in the inlet tube has formed the water seal, lead to the ventilation to be obstructed, make the current of air inlet fan 8 too high, can be to water injection in the inlet tube this moment, make under air inlet fan 8's effect, the water level of the water in the inlet tube can rise fast, until reaching the siphon height, thereby trigger the water discharge of siphon device in with the inlet tube, when air inlet fan 8's current does not reach preset current value, explain that the water in the inlet tube does not form the water seal, air inlet fan 8 can directly realize the ventilation of a section of thick bamboo subassembly this moment. It should be noted that the preset current value may also be set to a current value corresponding to when the water in the water inlet pipe approaches to form water seal, for example, when the water in the water inlet pipe is more, although ventilation is not completely blocked, the ventilation capability at this time is very limited, at this time, a water inlet mode into the water inlet pipe may be adopted to quickly raise the water level in the water inlet pipe under the action of the air intake fan, and then the water in the water inlet pipe is discharged, so that the air circulation area in the water inlet pipe is increased to ensure subsequent ventilation operation, a person skilled in the art may flexibly set the water seal condition corresponding to the preset current value in practical application, as long as a boundary point determined by the preset current value is used to distinguish whether it is necessary to inject water into the water inlet pipe to trigger siphon phenomenon to release water seal, the preset current value may be determined before the drum washing machine leaves the factory, it may also be determined when the drum washing machine is used for the first time after entering the home of the user. In the above, the water inlet valve of the drum washing machine is preferably directly opened to allow the external water to enter the laundry treating agent feeding box through the water inlet valve and then enter the water inlet pipe, and of course, other water injection methods may be adopted, such as a water inlet valve separately disposed on the water inlet pipe and controlling the water injection operation to the water inlet pipe through the water inlet valve.
In one possible case, as shown in fig. 6, the ventilation control method of the present invention includes:
s1: after the drum washing machine finishes washing, the air inlet fan 8 is started;
s2: acquiring the current of the air inlet fan 8;
s31: if the current of the air inlet fan 8 reaches a preset current value, opening the water inlet valve for 2s, and then ventilating the outer barrel;
s32: if the current of the air inlet fan 8 does not reach the preset current value, directly ventilating the outer cylinder;
s4: the inner cylinder 3 is rotated.
In step S4, if there are clothes in the inner tub 3, the clothes can be shaken out and the air drying of the tub assembly can be realized.
In step S31, instead of directly setting the opening time of the water inlet valve, the water level in the water inlet pipe may be detected by providing a water level sensor in the water inlet pipe, and the water inlet valve is controlled to be closed when the detected water level in the water inlet pipe reaches the siphon height.
Under the condition that a water seal is formed in the water inlet pipe, after the air inlet fan 8 is opened, external air can be introduced into the outer barrel 2 through the air inlet pipe 7, the air in the outer barrel 2 can enter the water inlet pipe, water is arranged in the water inlet pipe and forms the water seal, the water level in the siphon device can rise under the action of air pressure after the air enters the water inlet pipe, then water is injected into the water inlet pipe, the water level in the water inlet pipe rises rapidly until the siphon device is triggered to generate a siphon phenomenon, the siphon device can discharge the water in the water inlet pipe, the water seal in the water inlet pipe is removed, the air in the outer barrel 2 can continue to enter the clothing treating agent feeding box 5 after entering the water inlet pipe, the clothing treating agent feeding box 5 is communicated with the outside, the inside of the outer barrel 2 is in a conduction state, and ventilation is realized under the action of the air inlet fan 8, thereby air-dry the inside of section of thick bamboo subassembly and discharge the peculiar smell in the section of thick bamboo subassembly simultaneously, avoid breeding the bacterium and produce secondary pollution to the washing of follow-up clothing.
Preferably, as shown in fig. 1 to 5, the inlet pipe is a U-shaped inlet pipe 6, the siphon device is a siphon 9, and the siphon trigger position of the siphon 9 is located between the height position of the inlet of the U-shaped inlet pipe 6 and the height position of the outlet of the U-shaped inlet pipe 6. When the drum washing machine is normally used for washing, water is firstly injected into the outer barrel 2, external water (generally connected with tap water) enters the clothes treating agent feeding box 5 and then enters the U-shaped water inlet pipe 6 through the inlet of the U-shaped water inlet pipe 6, the water level in the U-shaped water inlet pipe 6 is continuously raised and enters the outer barrel 2 through the outlet of the U-shaped water inlet pipe 6, the siphon triggering position of the siphon pipe 9 is higher than the outlet of the U-shaped water inlet pipe 6, water in the U-shaped water inlet pipe 6 can only enter the outer barrel 2 due to the principle of a communicating device and cannot cause the siphon pipe 9 to trigger the siphon phenomenon, and after the water injection is completed, water is stored in the U-shaped water inlet pipe 6 and completely seals the transverse section and at least a part of the U-shaped water inlet pipe 6, namely, the U-shaped water inlet pipe 6 is subjected to water sealing (as shown in fig. 3). When the drum washing machine executes a ventilation program, the air inlet fan 8 is turned on, outside air is introduced into the air inlet pipe 7 by the air inlet fan 8, then the air enters the outer barrel 2 again, the air in the outer barrel 2 enters the U-shaped water inlet pipe 6 through the outlet of the U-shaped water inlet pipe 6, then downward pressure is applied to water in the U-shaped water inlet pipe 6 under the action of air pressure, so that the water level in the siphon pipe 9 rises (as shown in fig. 4), when the water injection operation is performed on the U-shaped water inlet pipe 6 in a matching manner, the water level in the U-shaped water inlet pipe 6 rises rapidly until reaching a siphon trigger position (namely the siphon height), the siphon pipe 9 discharges the water in the U-shaped water inlet pipe 6, so that the water seal of the U-shaped water inlet pipe 6 is released, and further, the gas can enter the laundry treating agent putting box 5 through the inlet of the U-shaped water inlet pipe 6 and then is discharged to the outside (as shown in fig. 5), and because the siphon trigger position of siphon 9 is lower than the inlet of U-shaped inlet tube 6, the water in U-shaped inlet tube 6 can not enter into the laundry treating agent feeding box 5, and further the overflow condition of the drum washing machine can not occur. In the above, as an alternative, the U-shaped water inlet pipe 6 may be replaced by a V-shaped water inlet pipe, etc., and those skilled in the art can flexibly set the shape and structural style of the water inlet pipe according to the internal arrangement space of the drum washing machine in practical application, and such adjustment and change of the shape and structural style of the water inlet pipe do not form a limitation to the present invention, and should be limited within the protection scope of the present invention. In a preferred case, the siphon 9 communicates with the bottom of the transverse section of the U-shaped water inlet pipe 6, by means of which arrangement the water in the U-shaped water inlet pipe 6 can be completely emptied, avoiding the occurrence of residues, when the drum washing machine performs a ventilation program.
In addition, the air inlet pipe 7 can be communicated with the outer barrel 2, and can also be communicated with the fold part of the window pad 4, of course, the most preferable is communicated with the fold part of the window pad 4, through the arrangement, the external air can enter the fold part of the window pad 4 firstly and then enter the outer barrel 2, the fold part of the window pad 4 and the outer barrel 2 can be dried simultaneously, no dead angle in the barrel assembly is dried, bacteria breeding in the barrel assembly is avoided, the barrel assembly does not need to be cleaned repeatedly by a user, and secondary pollution to subsequently washed clothes can be avoided. Further, when the air inlet duct 7 communicates with the outer tub 2, preferably with the top of the outer tub 2, it is prevented that water in the outer tub 2 flows back into the air inlet duct 7 during washing, and when the air inlet duct 7 communicates with the corrugated portion of the window mat 4, preferably with the top of the corrugated portion of the window mat 4, it is also prevented that water in the outer tub 2 flows back into the air inlet duct 7 during washing.
Preferably, as shown in fig. 1, a foam overflow preventing member 10 is disposed in the air inlet pipe 7, and the foam overflow preventing member 10 may be a one-way valve, and may also be a combined structure of dampers. For example, the anti-foam overflow member 10 includes a door body, a first permanent magnet and a second permanent magnet, the door body is rotatably disposed in the air inlet pipe, the first permanent magnet is disposed on the door body, the second permanent magnet is disposed on the upstream side of the door body along the air inlet direction of the air inlet pipe, the first permanent magnet and the second permanent magnet have different magnetism, after the air inlet fan 8 is opened, the air flow generated by the air inlet fan 8 can overcome the suction force between the first permanent magnet and the second permanent magnet to rotate the door body from the closed position to the open position, so that the external air enters the outer barrel 2, when the air inlet fan 8 is stopped, the door body is kept at the closed position by the suction force between the first permanent magnet and the second permanent magnet, thereby preventing foam overflow. For another example, the anti-foam overflow component 10 includes a door body, a first permanent magnet and a second permanent magnet, the door body is rotatably disposed in the air inlet pipe, the first permanent magnet is disposed on the door body, the air flow direction of the air inlet pipe of the second permanent magnet is disposed on the downstream side of the door body, the first permanent magnet and the second permanent magnet have the same magnetism, after the air inlet fan 8 is opened, the air flow generated by the air inlet fan 8 can overcome the repulsive force between the first permanent magnet and the second permanent magnet to rotate the door body from the closed position to the open position, so that the external air enters the outer barrel 2, and when the air inlet fan 8 is stopped, the door body is kept at the closed position by the repulsive force between the first permanent magnet and the second permanent magnet, so as to prevent the foam overflow. Of course, the first permanent magnet and the second permanent magnet may also be replaced by elastic torsion springs, that is, the door body is rotatably disposed in the air inlet pipe 7 through the elastic torsion springs, the opening of the air inlet fan 8 enables the door body to open the air inlet pipe 7 by overcoming the torsion of the elastic torsion springs, and the elastic torsion springs enable the door body to reset to close the air inlet pipe 7 after the air inlet fan 8 is closed. Those skilled in the art can flexibly set the specific structure of the anti-foam overflow component 10 in practical application, and such adjustment and modification to the specific structure of the anti-foam overflow component 10 should not be construed as limiting the scope of the present invention. In a preferred case, the air intake fan 8 is disposed at the upstream side of the anti-foam overflow member 10 along the air intake direction of the air intake duct 7, so that the air intake fan 8 does not contact foam to cause a short-circuit condition, thereby improving the safety of the drum washing machine.
Preferably, an air filtering member is disposed in the air inlet pipe 7, and the air filtering member may adopt a single-stage filtering net or a multi-stage filtering net structure, or adopt other filtering structures, so as to prevent external dirt from entering the outer tub 2.
